Value Collection C50000313 Flooring Screws 3in 5/16-18

Product Description

The VALUE COLLECTION C50000313 is a steel flooring screw designed for structural subfloor and hardwood flooring fastening applications. At 3 inches in overall length with a 5/16-18 thread size, this screw is built to pull floor decking tight and hold under repeated load and seasonal movement. The black phosphate finish provides corrosion resistance and reduces surface glare during installation. Drive engagement uses a T40 Torx-style bit, which reduces cam-out risk compared to hex or square drives when working at high torque. Each package contains 100 screws, sized for job-site use by flooring contractors and framing crews.

These flooring screws are suited for residential and light commercial subfloor fastening, structural decking attachment, and hardwood or engineered floor system installations. The 5/16-18 coarse thread pattern is appropriate for wood-to-wood or wood-to-structural member connections where a strong mechanical grip is required. Flooring mechanics, finish carpenters, and framing crews will find these screws appropriate for situations where ring-shank nails or pneumatic fasteners are not practical or permitted by the scope of work.

Key Features

• 3-inch overall length provides deep penetration into subfloor and joist for secure holding strength
• 5/16-18 thread size delivers a coarse, high-grip thread pattern suited for wood structural fastening
• Black phosphate finish adds corrosion resistance and minimizes light reflection during install
• T40 Torx drive reduces cam-out under high-torque driving conditions
• Steel construction provides consistent tensile and shear strength across the fastener
• 100-count packaging supports continuous work without frequent restocking

Compatibility

Designed as a general-purpose flooring screw for use in wood subfloor, hardwood flooring, and structural decking fastening applications where a 5/16-18 thread profile and 3-inch length are specified.

Installation Notes

Installation should be performed by a qualified flooring contractor or carpenter following applicable building code requirements for fastener spacing and penetration depth. Use a T40 Torx driver bit and an impact driver or drill set to appropriate torque to avoid overdriving and countersinking beyond the intended depth. Pre-drilling a pilot hole is recommended when fastening near board edges to prevent splitting. Always confirm that the fastener length and thread size are appropriate for the specific subfloor assembly and joist system before installation.
